Model number LN-S4051D. How do I correct a pixel issue?


Burned pixels cannot be repaired, they are individual elements of the screen that have failed. You would need to replace the actual LCD panel.

Try changing the input device to something that works. If the display is same, there is a damage to the display and might need replacement.

White dots appearing on screen, also have black dots if you look closely...


It can be pixel problem. Every pixel has one transistor to switch off or on. I hate how manufacturers treat us because lot of them 'believe' that this is not a problem (must be more than 6-8 pixel problem on screen for changing). Sometimes little press with finger and shutting down screen can help, but it is possible to do worse if it is to hard press. Price for screens depend on that tolerating of bad pixels from manufacturing. Only few manufacturer can give you guarantee pixel free screen. It is good to know that we have right to return device after buying if we are not satisfy.

There is a black spot in the screen. How do I get it out?


Hello:
LCD TVs have millions of "pixels" that change color to make up a complete picture. Sometimes in the manufacturing process, pixels can become damaged (called "dead pixels"). There is no way for the consumer to fix these. Most manufacturers have a certain number of pixels that are "allowed" to be broken before they will fix it.
You should contact either the vendor you purchased the TV from, or Polaroid support.
You can contact Polaroid Support at 1-800-POLAROID (1-800-765-2764).

I would like to know my full hd lcd tv was repalced with new panel due to pixel burnt. how do i acertain the panel is changed with the same part because i have seen HD lcd tv looks alike .


Well if it dosn't have the burnt pixel showing then it was changed. You can't"fix" a pixel. I am surprised that it was returned for replacement as samsung have a policy that says 3 pixels is an acceptable expectation and not warrantable.

Black line half way down the center of the screen,about 1.5 inche


There's a 'data control' and/or 'address' problem that's developed. Pixels depend on voltage, control, and data coming too their designated address.

A digital circuit feature called a 'DATA_ADDRESS_ BUS" are responsible for 3 criteria: Delivering voltage, control, and data to each pixel in less than a second.

1) If voltage fails the pixels don't light up. They appear black in color (their 'off 'state)....numerous pixels that don't light up look like a black line. But their actually individual pixels with no voltage.

2) If control fails then all pixels are white in color (their 'on' state). Without control the pixels can't adjust properly to high or low 'state', meaning brightness and dimness. This looks like a white line vertically on the screen.

3) If data fails then the pixels can't adjust to the proper color at the proper time.
This appears as a line that changes color out of sync with the entire picture.


Have a technician look at the pixel address registry circuits. As well as control and linear circuits....the problem is somewhere in there!

Changing pixel setting


First thing is make sure you are using component video cables. The setting you need is most likely in the dish box setup. Go into the menu and look for the setting for the output resolution.
